Dyspnoea Management Questionnaire
Objective[edit | edit source]
Dyspnoea represents one of the most frequent cardinal symptoms globaly.It is a sensation of lacking of the air and of not being able to breathe normally.DMQ was developed in USA to measure the effect of lung rehabilitation and change over time in patients with COPD.Dyspnoea Management Questionnaire (DMQ) used in clinical and research settings for measuring treatment outcomes for patients with chronic obstructive lung disease (COPD).[1]
Data from qualitative interviews, literature review on the areas of breathlessness, anxiety, avoidance behaviour, functional status, health related quality of life, user satisfaction, and lung rehabilitation, as well as a review of other measurement instruments, made up the basis for the development of DMQ-30.
The resulting DMQ is a 30-item scale that measures 5 conceptually derived dimensions: dyspnea intensity, dyspnea-related anxiety, fearful activity avoidance, self-efficacy for activity, and satisfaction with strategy use. It has a 7-point Likert-type scale and third Flesch-Kincaid reading grade level. A panel of 12 experts supported the content validity of the DMQ. It showed high internal consistency (alpha = .87 to .96) and test-retest reliability over 2.5 weeks (intraclass correlation coefficient = 0.71 to 0.95).The DMQ addresses the need for a more comprehensive, multidimensional assessment of dyspnea, especially for anxious patients with COPD, in order to better guide the appropriate application of dyspnea management interventions and measure pulmonary rehabilitation outcomes.[2]
The DMQ demonstrated acceptable levels of reliability and validity for measuring multidimensional dyspnea outcomes after medical, psychological, and behavioral interventions for adults with COPD.. The DMQ-56 showed good internal consistency reliability (α = 0.85-to 0.96) and good preliminary test-retest reliability over a 3-week interval (ICC = 0.69-0.92).[3]
Method of Use[edit | edit source]
- The DMQ consists of five theoretical dyspnea dimensions:
- dyspnea intensity,
- dyspnea anxiety,
- activity avoidance,
- activity self-efficacy, and
- satisfaction with strategy use.
- The DMQ uses a 7-point Likert response scale that ranges from 0 to 6 with higher scores representing better dyspnea-related function.
- For example, the activity avoidance scale of the DMQ ranges from (6) “never” to (0) “all the time”.
- To calculate each subscale score, raw values for items are summed and then divided by the number of items in the subscale to obtain a mean score.
- The DMQ was developed to be both a clinical and a research outcome scale to measure the effectiveness of multi-disciplinary treatments that aim to reduce the emotionally distressing and disabling responses to dyspnea and promote adaptive coping for adults with COPD.[1]
